Description

This application report describes the implementation of the radix-4 decimation in frequency (DIF) fast Fourier transform (FFT) algorithm using the Texas Instruments (TI(TM)) TMS320C80 digital signal processor (DSP). The radix-4 DIF algorithm increases the execution speed of the FFT.Each TMS320C80 DSP parallel processor (PP) contains four major units operating in parallel. This parallel operati
